DIVIDERS.

Specification of Letters Patent.

Patented Apr. 30, 1918.

Application filed January 12, 1916. Serial No. 71,707.

To all whom it may concern:

Be it known. that I, WILLIE I. PALMER, a citizen of the United States, residin at Wheatland, in the county of Platte, tate of Wyoming, have invented certain new and useful Improvements in Dividers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention is directed to improvements in dividers, and has for its object to so construct a device of this character to accurately ascertain the distance between the points of the le thereof.

A further object o the invention is to provide a divider having a graduated bar carried thereby to indicate accurately the distance measured between the points of the legs thereof.

A still further object of the invention is to Provide a novel means for locking the legs of the device in their adjusted positions.

With these and other objects in View, this invention resides in the novel features of construction, formation, combination and arrangement of arts to be hereinafter more fully described: claimed and illustrated in the accompanying drawing, in which Figure 1 is a front elevation of the device.

Fig. 2 is a side elevation.

Fig. 3 is a sectional view on line 33 of The device comprises a pair of legs 1 and 2, which are hingedly connected at their upper ends, as at 3, said legs having their lower ends provided, as is usual, with points 4. Having one end fixed intermediate the ends of the leg 2 and lying in position to extend across the leg 1, is an arcuate bar 5, said bar havin marked thereon graduations to indicate tl ie distance between the points 4, and also having marked thereon adjacent its fixed end an indicating mark 6 in a line with the marking oint of the leg 2, the purpose of which will appear later.

A bolt 7 is passed through the le 1 and through a block 8, which is soldere to the adjacent face of the leg gaged on the bolt 7 is a thumb nut 9 which has its base of such diameter that it will overhang the bar 5, whereby when the nut is rotated in one direction it will bindingly engage the bar to hold the legs 1 and 2 in their set position so that the graduations can be read to ascertain the distance found between the points 4 of the legs.

Having its outer end fixed to the leg 1 and extending oppositely to the bar in position to extend across the leg 1, is an arcuate bar 10 which is of less length than the bar 5, said bar also having marked thereon an indicatin mark 11 which is placed adjacent the xed end thereof and in a line with the marking point of the leg 1. It will be noted that the adjacent edges of the bars 5 and 10 slidably engage each other when the legs are spread apart or moved toward each other.

The bar 10 may be employed, in connection with the scale on the plate 5, as a vernier scale and may also be used as an additional width indicating scale, said bar 10 being marked with graduations designating tenths of a foot, whereby when one of the graduations thereon coincide with the mark 6 on the bar 5 it will indicate the distance between the points 4 of the legs.

It will be of course understood that when a graduation on the bar 5 coincides with the mark 11 on the bar 10, it will indicate the distance in inches between the points 4, and which is conventionally used by draftsmen, whereas the graduations on the bar 10 representing tenths of a foot are principal used by engineers who usually employ suc scale.

What is claimed is A divider having an arcuate bar fixed at one end to one of its legs and lying in osition to extend across the other leg and aving raduations thereon, a second bar secure at one end to the other leg and lying 1. Adjustably enin a position to extend across the first lnenmeans for locking the legs against move- 10 tloned leg, said bars having their mutually ment.

adjacent edges disposed in sliding engage- In testimony whereof, afiix my signature, ment, each of said bars having graduetions 1n the presence of two witnesses. marked thereon and each having marked WILLIE I. PALMER thereon also an indieatin mark in a line with the marking point 0 the leg to Which Witnesses:

the bar is attached in position to coincide KENT SNYDER, with the gradnations of the other bin", and Osooon JOHNSON.
